For Proof-of-work, one wants to incentivize many miners to join the network and mine blocks and thereby increase the security of the network. Others agree the reward is too high at present; the upcoming Constantinople hard fork will reduce the block reward from 3 to 2. I think the developers didn't anticipate that it would take so long to get to proof-of-stake, and also did not anticipate that the price of Ether would go so high and thereby bring so much mining power on board.
